Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.

Explanation:
DNA encoded all genetic information that has to be transferred from generation to generation
The correct option is that the higher the temperature of Y the more colorless cells it contains and is denoted as option B.
<h3>What is Temperature?</h3>
This us defined as the degree of hotness or coldness of a body and is dependent on thermal energy.
High temperature will denature yeast as a result of its rich protein content and increasing the temperature will therefore leads to the presence of more colorless cells in Y which are able to act on it.
